Product Description:
The 8MSA8X.E1-M2 Servo motor of the B & R Automation is designed for continuous operation in industrial automation operations. The motor achieves a maximum speed of 3600 rpm. It maintains a nominal speed of 2000 rpm under normal conditions. This servo motor operates with a rated current of 35.8 A during standard loads.
The stall torque provided by the 8MSA8X.E1-M2 servo motor reaches 115 Nm. The peak torque is rated at 345 Nm. This allows it to handle temporary high-load conditions efficiently. The peak current capacity is 182 A to allow brief surges in power demand. The torque constant is measured at 2.46 Nm per ampere. It draws a stall current of 46.66 A when stationary under load. Its rated torque is specified at 85 Nm to ensure a consistent output during continuous use. The voltage constant is rated at 149 V per 1000 rpm, which helps define the back EMF characteristics. The 8MSA8X.E1-M2 servo motor can accelerate at a maximum rate of 18148 rad/s² without an integrated brake system. The stator inductance is 2.8 mH. It contributes to stable electrical behavior during dynamic operations. Its electrical time constant is 31.11 milliseconds. The thermal time constant of 90 minutes provides prolonged heat dissipation. The connection direction is oriented on the A side. It has six poles to support effective torque production.
The 8MSA8X.E1-M2 servo motor features a stator resistance of 0.09 ohms to support efficient power usage. The motor weighs 89 kg without a brake and features a moment of inertia of 190.1 kg·cm², aiding motion stability. Mechanically, the motor includes a smooth shaft end for diverse connection options. The insulation class is F to allow the operation at higher temperatures. The IP64 protection rating applies when used without an oil seal.
